METHOD OF MANUFACTURING LUBRICANTS.

SPECIFICATION forming part of Letters Patent N 0. 787,545, dated April 18 1905. Application filed April 26, 1904. Serial No. 205,048.

To all whom it may concern:

Be it known that we, GEORGE W. VANDER- sLIoE, residing at Clayton, in the county of Gloucester, State of New Jersey, and JAMEs RILEY, residing at Trenton, in the county of Grundy, State of Missouri, citizens of the United States, have invented a new and useful Method of Manufacturing Lubricants, of which the following is a specification.

In carrying outour invention we take a quantity of oil, such as petroleum or hydrocarbon fluid or oil or compounds thereof, and place the same in a suitable vessel or tank and bring it to a boil. We then draw ofi the oil while in its hot condition and place it in another suitable vessel or tank without further boiling, adding to each gallon thereof, more or less, one-quarter of a pound of Wood, more or less, such as cedar or cherry, shredded or ground preferably in the condition of excelsior, the wood being placed in a cage with fine mesh to keep it separate from the oil, while, however, allowing commingling of the oil and wood, whereby the resin or gum in the wood is extracted therefrom and combined with the oil, being held in solution therein. The spent wood is then removed from the oil, and the latter is then in condition for use, it being of superior order for the purpose intended.

Having thus described our invention, what we claim as new, and desire to secure by Let ters Patent, is-

1. The method of forming a lubricant consisting in taking a suitable lubricating-oil, boiling the same, adding wood to the hot oil, whereby resin in the former is extracted and combined with the latter and then removing the spent wood leaving the resultant oil in condition for use.

. 2. The method of forming a lubricant consisting in taking a suitable lubricating-oil,
